Specific embodiment
The utility model is further described with the following Examples.
Fig. 1 is the structural schematic diagram of the charging pile of the present embodiment, and wherein charging pile is specially to exchange portable charged stake, is filled
One end of the pile body 2 of electric stake is equipped with 10A plug 11 and 16A plug 12, and the other end of pile body 2 is equipped with charging gun 3.Wherein,
As shown in Fig. 2, 10A plug 11 and 16A plug 12 are connected jointly on single-phase electric wire (L line, N line, E line).
See Fig. 3, is connected after passing through pile body 2 with the single-phase electric wire that plug connects with charging gun 3.Work is equipped in pile body 2
Make circuit, which includes charge-discharge control circuit 22 and controller 21.Routine is equipped in charge-discharge control circuit 22
Two relays K1, K2, relay K1 are connected in the L line in single-phase electric wire, and relay K2 is connected on the N line in single-phase electric wire
In, the controller 21 in pile body 2 controls the ON/OFF of relay K1, K2.Due to relay K1, K2 and its control circuit
For the prior art, do not repeat excessively herein.Conventional signal wire (not shown) is connected between pile body 2 and charging gun 3,
Including CP line, CC line, then signal wire and vehicle-mounted BMS system establish connection to the charge and discharge electrical interface of the insertion electric car of charging gun 3.
See that Fig. 4, the side wall of 10A plug 11 are a circle round tube 113, round tube 113 has the inner ring 112 of unilateral protrusion, inner ring
112 are located at the front end of round tube 113 and fix with round tube 113.The exposed end face of inner ring 112 has panel 111, and panel 111 should
End face seal is got up.There is the tri- foot inserted sheet of 10A being connected with single-phase electric wire (not shown go out), tri- foot inserted sheet of 10A on panel 111
Specification meet national standard.The tray shaped recess 115 that the rear end of round tube 113 is fixed with for the docking insertion of inner ring 112, dish type
Groove 115 is embedded in round tube 113.The slot bottom of tray shaped recess 115 has inside groove 1151, which forms a collection portion,
For tri- foot inserted sheet of the 16A insertion for 12 front end of 16A plug to hidden.The slot bottom of tray shaped recess 115 is provided with circular hole
1152, there is safety switch SJ1 be electrically connected with controller 21, the contact of safety switch SJ1 is across circular hole inside round tube 113
1152 so that appear the slot bottom of tray shaped recess 115.
The structure of 16A plug 12 is identical as the structure of 10A plug 11, and details are not described herein again.But the front end of 16A plug 12 is
Tri- foot inserted sheet of 16A rather than tri- foot inserted sheet of 10A, the specification, size of the two be not identical；Safety switch inside 16A plug 12 claims
For SJ2.
When being charged with charging pile, if commercial power socket is 16A socket, user can be by the inner ring of 11 front end of 10A plug
It is inserted into the tray shaped recess of 12 rear end of 16A plug, then the front end insertion 16A socket of 16A plug 12 is taken into electricity.By 10A plug
11 front ends are inserted into after 12 rear end of 16A plug, and the panel of 11 front end of 10A plug can squeeze safety switch SJ2 in 16A plug 12
Contact is connected safety switch SJ2 to controller 21 and sends signal.Controller 21 accordingly know and use 16A plug 12 by signal
Electricity is taken, then standard PWM signal corresponding to high-power charge mode is sent (referred to as to the BMS system of electric car by CP line
PWM_A).According to the prior art, if vehicle end needs to charge, the BMS system at vehicle end can be to the CC terminal of vehicle end charge and discharge electrical interface
Connection status judged, and then confirm the normal insertion charge and discharge electrical interface of charging gun 3, and change after receiving PWM_A
The voltage amplitude of the signal, with this 21 successful connection of notification controller, realization is shaken hands；Then BMS system can also be according to PWM_A
Duty ratio asks for the electric current of corresponding standard size to charging pile, and 16A socket is enable to afford charging pile without burning.Control
Device 21 processed changes signal as feedback signal, to recognize success of whether shaking hands using the voltage amplitude of this PWM_A.If controller 21
Feedback signal is received, then means success of shaking hands, charging pile has been prepared for charging, then relay K1, K2 conducting are controlled,
The electric energy for enabling 16A plug 12 to be taken is circulated on charging gun 3, is charged to vehicle；If being otherwise failure to actuate.
If commercial power socket is 10A socket, 12 front end of 16A plug is inserted into 11 rear end of 10A plug by user, then will
The front end insertion 10A socket of 10A plug 11 takes electricity.In this case, the safety switch SJ1 in 10A plug 11 is connected, controller 21
Standard PWM signal (abbreviation PWM_B) corresponding to small-power charge mode is sent to BMS system.Equally, if vehicle end needs to charge
And electric rifle is normally inserted into charge and discharge electrical interface, then vehicle end can change the voltage amplitude of PWM_B, and according to the duty ratio of PWM_B come
The electric current that corresponding standard is asked for charging pile enables 10A socket to afford charging pile without burning.Controller 21 recognizes
The voltage amplitude of PWM_B changes, then illustrates success of shaking hands, and controls relay K1, K2 conducting, makes tri- foot inserted sheet institute of 10A
The electric energy taken is able to be circulated on charging gun 3；If being otherwise failure to actuate.
Further, see Fig. 4,112 outer wall of inner ring of 11 front end of 10A plug protrudes outwardly forms shackle member 1121,10A
There is rotation card slot 1153, rotation card slot 1153 and shackle member 1121 are suitable on the inner sidewall of the tray shaped recess 115 of 11 rear end of plug
Match.16A plug 12 also is provided with shackle member and rotation card slot.After 10A plug is inserted into 12 rear end of 16A plug, rotation 10A is inserted
First 11, the shackle member of 10A plug 11 can be made to be caught in the rotation card slot of 16A plug 12 and locked；Vice versa.
Pile body 2 is built-in with take-up reel for the cable winding on power input interface or charging gun 3 to pile body 2
Interior, wherein the specific structure of take-up reel can refer to the patent application 201810098502.0 of our company.It should be noted that can also
To remove take-up reel, and the shape of single-phase electric wire is become into spring wire, to achieve the purpose that store cable.
Also with relay Control peripheral circuit, the controller internal circuit, power module of charging pile routine in pile body 2
Deng being routine techniques, details are not described herein again.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
